Section targeting is the sophisticated way to attract relevent ads to the site content.Section targeting helps us to emphasize or downpaly ads to the content of the site.For section targeting you have to add a set of HTML comment tags into your code. In the very first line (Relevant ads to the site content plays an important role to boost your adsense earning) of this article I have two key words 'adsense' and 'earning'. I want to display adsense ads relevent to 'adsense' and 'earning'. you have to add the sentence or particular words "adsense' and "earning" to be targeted.
The HTML tags to emphasize a page section take the following format:
<!-- google_ad_section_start -->
Relevant ads to the site content plays an important role to boost your adsense earning
<!-- google_ad_section_end -->
Suppose you do not want to display ads relevent to "AdSense'. You can de-emphasize it by adding (weight=ignore) to the starting tag. So it will look like
<!-- google_ad_section_start(weight=ignore) -->
AdSense
<!-- google_ad_section_end -->
your final code will look like the following.
(emphasized)
<html><head><title>Section targeting</title></head>
<!-- google_ad_section_start -->
your target text
<!-- google_ad_section_end -->
</body>
</html>
or
(de-emphasized)
<html><head><title>Section targeting</title></head>
<body>
<!-- google_ad_section_start(weight=ignore) -->
your target text
<!-- google_ad_section_end -->
</body>
</html>
You can use section targeting to make suggestions about as many sections of a page as you like. It may take upto 2 weeks to display relevent ads to your site content.
